I am Emacs (v24.5) newbie and I use it with ergoemacs-mode (v5.14.7.3.1) key-bindings.
I often need to edit data in YAML format manually and I do it in yaml-mode (v20160101.921) because of its highlighting and proper indenting.
However, when I try to set-mark in yaml-mode with ergoemacs-mode keys M-SPC it does nothing and only says:
edmacro-parse-keys: M- must prefix a single character, not SPc
Could you, please, suggest how can I make M-SPC behave in yaml-mode as it does everywhere else in Emacs (i.e., org-mode, ess).
Edit: Solved in newer version of ergoemacs-mode

I'm trying to get doremi working in emacs. Specifically, at this stage, to allow me to quickly scroll through a condensed list of color-themes and see each theme as I go through it. For this I would use the 'M-x doremi-color-themes+' command.
What I've done:
Installed color-themes (successfull)
Installed doremi.el, doremi-cmd.el, ring+.el and added
(add-to-list 'loadpath "~/elisp/themes")
(add-to-list 'loadpath "~/elisp/doremi/")
(require 'color-theme)
(color-theme-initialize)
(color-theme-classic)
;; create a list of color themes to scroll through using 'doremi-cmd
(setq my-color-themes (list 'color-theme-classic
'color-theme-retro-green
'color-theme-gray30
'color-theme-subtle-hacker
'color-theme-jonadabian-slate))
(require 'doremi)
(require 'doremi-cmd)
(require 'ring+)
to the .emacs file.
What emacs does:
When I type the comand 'M-x doremi-color-themes+' into the mini-buffer it seems to accept that I've given it a valid command and tells me to use the and arrow keys to move through the list. But when I do that all that happens is the cursor moves up and down in the active window. No changing of color-themes.
Being somewhat new to emacs (and especially customising it) I'm sure I have missed a step or put something in the wrong place. Perhaps there's some sort of (setq 'bla-bla-bla (...)) I need to do?
Sorry for your trouble. Please state your Emacs version (M-x emacs-version), and your version of color-theme.el.
You do not need to require library ring+.el if you use Emacs 23 or later (its code was included in GnuEmacs 23.)
You do not need to use (color-theme-initialize) or (color-theme-classic). The former is done automatically by doremi-color-themes+.
Try starting from emacs -Q (i.e., no init file, ~/.emacs), to be sure there is no interference from stuff in your init file.
Your variable my-color-themes is not referenced anywhere. Instead of defining that variable, just customize user option doremi-color-themes. (Or leave its value nil, which means that all color themes will be cycled through.)
Feel free to contact me by email if you continue to have a problem. Or continue here, if you prefer.
[Just to be sure: you are using color-theme.el, right? There is a lot of confusion out there between Emacs "custom themes" and color themes. Do Re Mi supports both, but they are different critters.]
After a bit for back and forth with #Drew we found a solution to the problem.
It turned out the major problem was that I was using emacs in 'terminal mode' rather than as a GUI application. Bare in mind I'm using a mac.
In the context of Terminal, my arrow keys send escape sequences and so doremi cannot read the event as intended. So it just escapes and applies the message to the active buffer.
There is an answer.
By adding the following lines to my .emacs file (or whatever your init file for emacs is) I was able to redirect doremi to use two other keys. ie. not the up and down arrows.
(setq doremi-down-keys '(?n))
(setq doremi-up-keys '(?p))
Doing this tells doremi to use 'n' as the down key and 'p' as the up key. And all works just fine.
Because I am only new to the world of programming and computing I may often use incorrect terminology. If this is the case please let me know and I will edit accordingly for clarity and consistency.
i am using emacs 23.2 and reference configurations from purcell https://github.com/purcell/emacs.d
i met a problem when i am edit ruby file and rails file, see below
steps:
1. move the cursor to somewhere
2. hit "RET" key to add more new line, then move the cursor to somewhere
3. the red space happened at the last new line.
do you know how to turn this mark off?
What's your problem with this feature? The red space goes away as soon as you
start typing doesn't it?
The feature is show-trailing-whitespace, and it's meant to help you see
spurious space at EOL. Which is very helpful for team development
environment, as checking in such code will annoy your teammates.
What you should do is add a before-save-hook that removes spurious
whitespace see:
http://www.emacswiki.org/emacs/DeletingWhitespace#toc3
code:
(add-hook 'before-save-hook 'delete-trailing-whitespace)
If you want to disable show-trailing-whitespace as well:
(add-hook 'ruby-mode-hook (lambda ()
(setq show-trailing-whitespace nil)))
You might like to look at the ws-trim.el library, which removes trailing whitespace from lines which you edit, but by default does not remove them from other lines*.
I find this best for version-control (compared to deleting all trailing whitespace upon saving), as you do not introduce changes in other people's work if you edit the same file.
(*) although it is also nicely configurable if you want it to do more than that.
I have just started learning Linux and Emacs. It was pleasant to have the same key bindings in both Emacs and a shell (bash/tcsh) for the most frequently used cursor movements, so that I do not have to consciously think which one I have to use. Still worse, use the wrong command and undo the mistake. There were two exceptions, though.
One often used command was the equivalent of backspace, delete a character backwards. In a shell, it was C-h. I got the same behaviour in Emacs, thanks to this tip from Janos, who probably felt the same way.
http://www.math.rutgers.edu/~komlos/emacs.htm
Now the mistake I do often in Emacs is trying to delete words backwards with the command M-C-h, as in a shell.
Can somebody please give a binding that will make Emacs delete words backwards with 'M-C-h'? Currently, this command selects the whole of the text in a buffer, which is quite an useful thing (C-a in windows), but not so frequently used as deleting words backwards.
Moreover, any binding to replace the current binding of M-h (from the link above) to help will be appreciated.
Thank you,
Elan.
Below binds C-M h to backward-kill-word. You can put it in your .emacs file.
(global-set-key (kbd "C-M-h") 'backward-kill-word)
You can use M-<backspace> in terminal and emacs to delete word backward.
It's best to use key translation so C-M-h works exactly the same as M-backspace would in any minor mode (regardless of whether M-backspace is bound to backward-kill-word or not).
;; bind C-h to <backspace>
(define-key key-translation-map [?\C-h] [?\C-?])
;; bind C-M-h to M-<backspace>
(define-key key-translation-map [?\C-\M-h] [?\C-\M-?])
I have found it annoying that flyspell seems to stay in the middle of the word when you do flyspell-auto-correct-word command. Can this be changed to force it to go to the end of the word after running the command? It might be as simple as setting a key binding to auto-complete-word and then move-forward-word which I know how to do. But this won't work in all cases because sometimes it puts the cursor behind the word if the auto-complete word was smaller than the typed word. Any help on this would be great.
Try this code:
(eval-after-load "flyspell"
'(defun flyspell-ajust-cursor-point (save cursor-location old-max)
(when (not (looking-at "\\b"))
(forward-word))))
Tested with flyspell version 1.7k, and with the version shipped with Emacs 23.2.
I looked through the (defun flyspell-auto-correct-word ...) and I can't see any good hooks or other customization points there so I think your best bet is to use C-h f defadvice:
(defadvice flyspell-auto-correct-word (after flyspell-forward-word activate) (flyspell-goto-next-error))
I'm having a hard time forcing literate-haskell-mode to produce PDFlatex output by default. When I use C-c C-t C-f it just parses the lhs file with latex binary producing dvi. I know I can always use the shell to manually run pdflatex whatever.lhs, but that's not the emacs way. There must be a way of customizing the default C-c C-t C-f behavior, but I've been googling and searching, and I still haven't found what I'm looking for.
Anyone?
Cheers;
Piotr
I guess this uses LaTeX-mode in the backend so probably something like this should help:
(setq TeX-PDF-mode t)
This tell LaTeX-mode to use pdflatex by default.
